Attractive, artistic, and more challenging than you might think, this 300-piece jigsaw puzzle for ages 3 and up features a 1921 illustration from Kling-Klang Gloria, a book of German folksongs and children's songs. The original was a lithograph in the art nouveau style—or Jugendstil—by artists Heinrich Lefler and Joseph Urban, and as such is heavily decorated with floral and checkerboard patterns on its large (1 1/2-inch) pieces. The finished puzzle is 24 x 18 inches.
